Sang Zhu, the maid of Shangshu Mansion, had witnessed the tragedy of young lady Ningxue's mismarriage in her previous life. Confused by appearances, Ningxue chose Gu Wenjie, the seemingly gentle and elegant number one scholar, but ignored General Qin Lie, who seemed rough but cared about his family and country. In the end, Ningxue's marriage was full of lies and disappointment, and Sang Zhu was misunderstood because of being reminded of the truth, and sadly passed away. At the moment when he was reborn and returned to make a choice, Sang Zhu was determined to use his eyes and heart to help Ningxue see people's hearts clearly.
